    Race condition in GpListener

    Keith McFarlane Newbie

      I get the dump below in the console at undetermined times when running TestJBossESB. It appears to originate in GpListener.WaitForCmdOrSleep, but I think it's caused by the potential of GpListener.millisToWait to return a negative value. Suggest you change to this:

      long millisToWait()
      {
      long waitTime = 0;
      return (((waitTime = (Math.min(m_lNextReload,m_lEndTime) -
      System.currentTimeMillis())) < 0)?0:waitTime);
      } //________________________________

      I've been testing & haven't seen the problem yet.
